METHOD OF FILTERING AND A DEVICE FOR FILTERING SOLID- CONTAINING LIQUIDS

摘要

In a filter pressure container provided with a plurality of vertically suspended tube-like filter elements having a filter cloth thereon the filtration of residual volumes of a liquid being filtered and the rinsing-out of the filter cakes built up during the filtration on the filter cloth are carried out by pumping out of the residual liquid or the rinsing liquid from the container by pump into an injector mounted in the container above the filter elements. The injector sprays out the residual liquid or the washing liquid over the filter elements while a pressure gas or air is simultaneously supplied into the container to force the liquid mist through the filter elements.
